Embodiment Construction

[0049] In the following description, the invention is illustrated in a motorcycle application.

[0050] figure 1 with figure 2 A general schematic view of a motorcycle 1 is shown provided with an inclination detection system 3 shown on the front wheel 5 . in addition, figure 1 shows the motorcycle 1 in a normal position according to one embodiment, and figure 2 Said motorcycle 1 according to the same embodiment is shown in a recumbent position.

[0051] The normal position of the motorcycle 1 corresponds to the vertical position of the motorcycle 1 in which said motorcycle 1 can drive normally. In contrast, the recumbent position of the motorcycle 1 corresponds to a position parallel to the ground, considered as a horizontal plane defined as being perpendicular to the direction of the gravity vector defining the vertical. Said motorcycle 1 is in the recumbent position, usually after an accident related to an event which may result in damage to the motorcycle 1 and resul...

Abstract

The present invention proposes a method for detecting an inclination of a wheel (5) of a motor vehicle (1) relative to the ground, said method comprising the following steps: measuring two accelerations by using two accelerometers which are mounted on the wheel (5) and are suitable for measuring the acceleration of the wheel (5) along a first axis (x) and along a second axis (z), respectively, the first axis (x) and the second axis (z) being in the plane of said wheel (5) and orthogonal; calculating, from the acceleration measurements, components of a gravity vector (G) in a coordinate system formed by the first axis (x) and the second axis (z); determining a modulus of the gravity vector (G) from the calculated components; and determining an inclination position of the wheel (5) relative to the ground by comparing the modulus value of the gravity vector (G) with a predetermined value.

Description

technical field [0001] The invention relates to a method of detecting the inclination of the wheels of a motor vehicle relative to the ground, considered as a horizontal plane defined as being perpendicular to the direction of a gravity vector defining a vertical. The invention also relates to a method of managing an engine when a motor vehicle is in an abnormal operating mode, for example after an accident or event that could lead to damage. [0002] The invention is suitable for use in motor vehicles, and in particular in the field of motorcycles. Background technique [0003] Motor vehicles comprise various safety systems which allow preventing accidents and also protect the occupants of the vehicle as well as the vehicle itself in the event of an accident. The current trend is to improve these safety systems in terms of efficiency, reliability and cost-effectiveness. [0004] Inclination sensors are used as on-board safety systems in motor vehicles in order to determin...
